Answer:
88.99
Step-by-step explanation:
his plan includes 800 minutes for 79.99, all we need to do is calculate the cost of the extra 50mins he used and add it to 79.99. this is ((850-800)*0.18) +79.99 and this is equal to 88.99
Estimate the sum in two different ways:
A) By rounding off to the highest place value (hundreds):
368 = 400 (3 hundreds is the highest place value)
231 = 200 (2 hundreds is the highest place value)
400 + 200 = 600
B) By rounding off to the second highest place value (tens):
368 = 370
231 = 230
370 + 230 = 600
Hope this helps!
21x-9+63=180
21x+54=180
21x=126
x=6
M= 2/3 that is the slope I hope this helps
